Recent research suggests a significant link between gut microbiota and anastomotic leakage (AL) in colorectal surgery. Patients who develop AL have a higher abundance of bacteria from the Lachnospiraceae family and lower microbial diversity.
Considering the bibliographic data, our main interest is to analyze the microbial population of patients in our social environment and then look for differences in the microbiome between those who have suffered an anastomotic dehiscence (around 8-9% according to the results of our hospital's Surgery Department) and those who have not.
